Bcoz sometimes the anime catch up with the manga too fast that they have to make fillers so the author of the manga has more time to produce more chapters.. Otherwise the anime has to be stop for a moment..

whats the big deal? if your hollow ichigo and i'm hollow ichigo it still doesn't make any difference.. unless both using the exact same avi that is.. Its just like when i first got into moddb i was kagami and i saw you and cr3mator were also kagami iirc..
